Bei Einsatz dickwandiger Halbzeuge mit entsprechend hoher Wärmekapazität eignen sich konventionelle Wärmebehandlungstechnologien und -prozessführungen jedoch nur eingeschränkt für einen effizienten Herstellungsprozess. Inhalt dieser Arbeit sind daher innovative Fertigungsstrategien, welche die wirtschaftliche Herstellung entsprechender Bauteile vor dem Hintergrund einer effektiven Formgebung sowie einer anforderungsangepassten Werkstoffbehandlung zum Ziel haben. Spezielle Temperaturführungsstrategien als auch thermomechanische Herangehensweisen zum Einstellen besonders günstiger mechanischer Eigenschaften entsprechender Stahlwerkstoffe stellen in diesem Kontext vielversprechende Ansatzpunkte dar.}},

Internal Flow-Turning is an innovative incremental forming technology which enables the manufacture of tubes featuring a varying wall thickness and a constant outer diameter. These characteristics facilitate the material feed at hydroforming processes significantly. In addition, the spinning-related forming technology improves the mechanical material properties, shape and dimensional accuracy, and the surface quality of parts produced.</jats:p>}},
